FREDERICK VILLARD, OF MOUNT EATON, OHIO.

Letters Patent No. 99,981,

dated February 15, 1870.

IMPROVED GRAIN-DRILL TOOTH.

The Schedule referred to in these Letters Patent and. making part or thesame.

Be it known that I, FREDERICK VILLARD, of Mount Eaton, in the county ofWayne, and State of Ohio, have invented a new and useful ImprovedGrain-Drill Tooth; and that the following is a sufiiciently full andexact description of the same to enable one skilled in the art to whichmy invention appertains to carry it intoefiect, reference being bad tothe accompanying drawings which'form part of this specification.

My invention relates to a tooth for grain-drills relieved from liabilityto clogging and dragging, adapted to have all requisite adjustmentsconveniently and ex- 1 peditiously made, andhaving its hopper so appliedas to be always supported in a horizontal or nearly horizontal position.

The drawings representa. grain-drill tooth embodying the improvements bywhich 1 effect the abovenamed objects, as applied to a beam, a portionof which is shown, andin a working positiou- Figure 1 being a plan view,partly in horizontal section;

Figure 2, a vertical longitudinal section on the line a: x,iig.1; and VFigure 3, a rear elevation.

The tooth proper or standard A is made hollow for the passage of theseed, is provided with a roller, B, working in a slot,-a, in its back atits lower end,which serves to support the tooth and thus preventdragging, and by its rotationby traction to keep clear the end of theseed passage, by forcing outward the earth, grass, and roots-whichmightotherwise enter and clog it; said wheel or roller being mounted inverticallyadjustable hearings, to adapt its action to be regulated asdesired. v

The wheel or roller B is mounted in the lower end of a slide or bracket,0, suitably constructed to receive it, and supported, first, by verticalguides a, formed on the back of the tooth or standard, as shown; second,a clamp-bolt, D, passing through an extension of the slot 01, providedin the back of the tooth or standard for the wheel or roller B, andthroughapeiibration in it, and provided on its outer end with athumb-nut, d,- or its equivalent; and third, a V-shaped projection, (1?,on the back of the tooth or standard above said slot, and a verticalseries of corresponding depressions, c, in its face; the formerprovision serving to support it laterally and the latter vertically atany desired point; its attachment by mea-ns of the clamp-bolt D dpassing through a vertical slot in the tooth or standard, adapting it tobe readily loosened and adjusted vertieally to any desired extent, andthen by tightening said screw and pressing one or another of thedepressions 0 over the projection a, to hold it.

The shovel or shoe'E may be of any desired form,

as to form the necessary-tight joint to and-attached in any suitablemanner.

The tooth proper constructed as above described is attached to the beamF through the medium of a frame is provided, by the introduction ofwhich, to a greater or lesser extent thereunder, the forward projectionof the tooth may be increased or diminished as desired, being secured inthedesired position bytighteuing the adjusting bolt H aforesaid.

To prevent the adj ustment of the angle of the tooth inj'nriouslyafi'ecting the position of the hopper J, it (the hopper) is attached toits support by horizontal pivots jj, parallel with that of the link, andadapted to beadjusted hy'means of a parallel bolt, K, passing through asegmental slot, j, therein, by which means I its horizontalityis adaptedto be preserved.

The. tooth is provided with the usual wooden-pin provision, to adapt itby the breakage of said pin to give way on coming in contact withany'solid obstacle;

and to prevent this efiecting the hopper when employed, or requiring itsdispensement, the base L of said hopper is made separate from theremaindcrof the tooth, and forms a part of or is attached separately it)the link G, thus receiving only the movement of said link and beam;thelower end of said base Land the top of the tooth or standard being soconstructed prevent the escape of seed, as shown in fig. 2. i

The tooth for the application of the wooden pinM is hinged to the rearextremity of the link or frame on its under side by means of lugs a o"embracing the rear-end of said link and a pintle, M, passingtherethrough, or in other suitable manner, and is provided in front withan upwardly projecting lug, a, provided with a transverse perforationcorresponding with similar ones in the sides of said link or frame,through which the wooden pin M is passed.

The staple. or clevis O for the attachment of the elevating chain may besecured between the rear ends of the double link or frame G by means ofthe pintlc N of the hinge of the tooth, as shown. i

The link or frame G and the'hopper base L may-be cast in two equallongitudinal parts, and united by means of two or more screws, P P, thefront of which may form the top of the yoke for the reception of theadjusting wedge I, as. fibown.

The principal ditiiculties with drill-teeth now in use are, that it theground is damp or contains grass, fibres; or roots to any great extent,the teeth fill up and consequently do not sow evenly, and the liabilityof the teeth to catch in the roots and similar obstructions and drag;both of which are seriously detrimental to the working of the machine,and render necessary the constant care of the operator.- Both of thesediliiculties are eli'ect-nally obviated by the provision of theground-wheel or roller at the sole of the tooth, as described; the toothbeing thereby supported and adapted to pass over ordinary obstructionswithout diflicnlty, and at the same timejthe seed-passage of the toothis kept perfectly clear, and thus a uniform and regular discharge ofseed ii'om' the tooth always obtained.

The mode of mounting and adjusting the hopper adapts it to be readilyused in connection with a folding-tooth, as described, and to receivethe seed with equal facility at any angle of the tooth.

The means for adjustment are simple and effective; and the tooth as awhole is strong, neat, and compact, and adapted to be readily andcheaply manufactured.

Having thus described my invention,

I claim and desire to secure by Letters Patent- 1. The combination, witha gmin-drill tooth, of a wheel or roller, B, arranged at its lower end,and adapted to be supported rigidly at such projection as to prevent thetooth dragging, as set forth.

2. The wheel or roller. B, employed and operating substantially asspecified, and mounted in verticallyadjustable bearings, substantiallyas shown and described, for the purposeset forth.

3. In combination with the pivoted link or frame G fillllllllg theattachment of the tooth to the beam, the segmental slot 9, bolts H H,yoke G, and notched wedge 1, arranged and operating substantially asdescribed, for the purpose set forth.

4. The hopper J, attached by transverse pivotal bolts jj, and adapted tobe adjusted to retain its horizontality, as described, for the purposeset forth.

5. The hopper base L, constructed separate from the tooth proper, asdescribed, tin the purpose set forth.

6. The combination of the link or frame G pivoted to the beam andadapted to be adjusted as desired, the tooth proper A E attached to saidlink or frame by means of a hinge-joint, a a" N, and wooden pin M, thewheel or roller B arranged in the lower end of the tooth and adapted tobe-adjusted vertically as desired, the hopper base L arranged on thelink or frame G separate from the tooth proper, and the hopper J mountedon thehase L and adapted to be adjusted as desired, substantially asrepresented and described, for the purpose set forth.
